Introduction
GB/T 34562—2017: In-depth interpretation of wool sound-absorbing and thermal insulation products standard
Background and significance of standard formulation
With the increasing demand for green and environmentally friendly materials in the construction industry, wool sound-absorbing and thermal insulation products have attracted widespread attention due to their excellent sound absorption and thermal insulation performance. The formulation of GB/T 34562—2017 "Wool Sound-absorbing and Thermal Insulation Products" standard fills the gap in this field in China and provides unified technical specifications and quality requirements for wool products used for sound absorption and thermal insulation in buildings.
Comparison of standard frameworks
| Standard dimensions | GB/T 34562—2017 | International alignment | Technical innovations |
|---|---|---|---|
| Definition of terms | Clear definition of wool sound-absorbing and thermal insulation products and their classification (felt, board, tube and shell) | Align with international standards to ensure uniform product naming | Introducing non-woven process technology requirements in China for the first time |
| Physical performance indicators | Key indicators such as thermal conductivity and noise reduction coefficient are clearly defined | Comply with international building energy-saving standards | New requirements for combustion performance and insect repellent residue |
| Test method | Use GB/T 10294 and other standards for arbitration testing | Consistent with relevant ISO standards | Optimized dimensional deviation and density control requirements |
Technology evolution analysis
The technological development of wool sound-absorbing and thermal insulation products has gone through the following stages:
- Initial exploration stage: Mainly study the basic properties of wool fibers and their applications in the field of thermal insulation.
- Process improvement stage: Introduce non-woven technology to improve the uniformity and stability of products.
- Standardization construction stage: Formulate unified national standards to regulate product production and testing methods.
Implementation suggestions and precautions
Case study: Application of wool sound-absorbing and heat-insulating products in construction
An office building uses wool sound-absorbing and heat-insulating panels in accordance with GB/T 34562-2017 standard, which significantly improves the indoor sound environment and thermal insulation performance. The following points should be noted during implementation:
- Strictly purchase products in accordance with standard requirements to ensure that product quality meets technical indicators.
- Pay attention to protecting the surface of materials during construction to avoid damage that affects the use effect.
- It is recommended to conduct performance tests after installation to ensure that the expected effect is achieved.
